The role of cold eggs
Cool egg cold eggs are also called cold eggs. It is a kind of operation procedure that opens the incubator door after the egg is hatched for a certain period of time, so that the temperature of the embryo egg is lowered. Because embryos develop large amounts of heat in the middle and later stages, cold eggs can dissipate the excess heat in the incubator, allowing the chick embryos to get fresh air, stimulating the embryos at a lower temperature, promoting the development of the chicks, and increasing the chick's future adaptation to outside temperatures. ability. The number and length of cold eggs should be determined based on the incubator's performance, embryo age, and season. In the early stages of hatching and cold weather, it should not be too cool, and late embryos and hot weather should be cooler. The specific cold egg time can be determined based on the egg temperature. Normally, after the seventh day of hatching, cool eggs are placed once a day in the morning and afternoon, and the electric heating and ventilation equipment is turned off. The hatch of the incubator is opened until the egg temperature drops to 30-33°C, and then the hatcher door is closed again to continue hatching. Embryo temperature can be felt with the eyelid, that is, sticking the egg to the eyelid and stopping the cool egg when it feels cool and cool. The modern heating system for incubators is well-designed and the heating is stable. In particular, incubators with cooling equipment do not require cool eggs during the incubation process. Only when the embryonic eggs hatch at hot season, the temperature of the embryonated eggs can cool the eggs properly. However, for incubators with inadequate ventilation systems, cool eggs must be used.
The function of syringe set mainly contains sealing function, tunnel permeability, tensile strength, puncture performance, degree of coordination, particulate contamination, reducing substances, metal ions, ph, ethylene oxide residue, sterility, bacterial endotoxin, cytotoxicity, sensitization, intradermal reaction, hemolysis, acute systemic toxicity, etc.
A mixing system sterile medicine mixer (powder and liquid ) is a device that mixes powder and injection before injecting the drug into the patient.But traditional booster injection infusion dispensing still exist, need medicine soluble medicine, when dispensing, repeated shocks and mixed extraction liquid, in the process of repeated puncture easy to produce plastic particles, particles stopper is getting into the human body easily blocked blood vessels, granulation, some problems of inflammation, and the ward of bacteria, viruses, repeatedly extracting liquid easy to carry the virus in the air, infusion to the solution of the problem.
